A novel temporal concealment technique that uses a grid-deformation motion model is proposed. A triangular mesh is superimposed on the damaged area, grid nodes are displaced according to a temporal prediction, and an affine transform is applied to interpolate the missing area. Experimental results show significant improvements compared to previously proposed approaches
